"After a mysterious woman gives Mike Bowditch disturbing news, the game warden goes looking for a family secret in a Maine ski town and discovers a vigilante who seems to be targeting sex offenders."--
Amber Langstrom claims her son Adam is a wrongfully convicted sex offender who has vanished from a brutal work camp in the high timber around the Widowmaker Ski Resort. She also claims that Adam is the illegitimate son of Jack Bowditch, Mike's dead father. Despite his reluctance to revisit his father's history of violence, Mike travels through a mountainous wilderness to a place where the military guards a top-secret interrogation base, sexual predators live together in a backwoods colony, and self-styled vigilantes are willing to murder anyone they consider their enemies.
